With their almost completely serpentine form and vaguely humanoid arms able to use weapons and tools, abominations were the form of yuan-ti that most closely resembled the originally intended appearance of the yuan-ti race as envisioned by the serpent gods.
Abominations often used scimitars in melee combat. They also attacked using their fangs, delivering a powerful poison. Abominations did not wear armor for their scales were more than enough to protect them.
Abominations were able to change their form into a viper of various sizes. They also had the ability to camouflage themselves and anything they carried to blend in with their surroundings. During melee combat, while holding onto an enemy, abominations could excrete a powerful acid from their skin. Abominations were capable of causing fear of snakes to any creature within 30 ft (9.1 m).
